Recovery from trauma isn’t a straight line. I doubt we knew his childhood trauma, and it’s irrelevant if we did or didn’t, as things could have surfaced a day after we signed him, or may never have done.
Money means he can pay for services yes but that won’t necessarily fix things, but wealth also adds expectation and responsibility whether they want it or not. And kids growing up wanting to be footballers, won’t understand the expectation on them and the way society is towards them until it’s too late, which is why we are seeing more and more players having issues with mental health. And for someone with childhood trauma, who has been through care as well, their social and emotional development will be considerably behind their peers, (there is research suggesting that their social/emotional development etc catches up to their peers by around age 30 though but it’s significantly delayed).
